what is inert pair effect ?

Expert Answer:

Inert pair effect: The tendency of the ns2 electron pair to participate in bond formation decreases with the increase in atomic size. Within a group, the higher oxidation state becomes less stable with respect to the lower oxidation state as the atomic number increases. This trend is called the inert pair effect. In other words, the energy required to unpair the ns2 electrons is more than the energy released in the formation of two additional bonds.
